We haven't heard much about the Infiniti Q50 Eau Rouge lately and it appears there is a pretty good reason why - it's dead.

We haven't heard much about the Infiniti Q50 Eau Rouge lately and it appears there is a pretty good reason why - it's dead.

While the news isn't terribly surprising since we've already heard rumors about its demise, Infiniti Europe vice president Francois Goupil de Bouille recently told Car Magazine the model has been shelved. As he explained, "It was just too costly. That was it. It is always a matter of balance of cost versus benefit, and we decided to reign in our costs." He went on to say the sales estimates for the model simply made it unrealistic to produce.

Originally introduced as a concept at the 2014 North American International Auto Show, the Q50 Eau Rouge received a lot of attention due to its Nissan GT-R sourced twin-turbo 3.8-liter V6 engine that developed 568 PS (417 kW). The reaction led the company to build several prototypes and consider a production variant but that's obviously not going to happen now.
